This disease is believed to be caused by immune cells (called lymphocytes) attacking tissue. Risk of death is highest in people with active acute disease. In addition, progressive Crohn's Disease leads to further loss of bowel function, which may eventually result in the need for artificial nutritional support (parenteral nutrition). This study involves high dose chemotherapy followed by return (infusion) of blood stem cells. Stem cells are undeveloped cells that have the capacity to grow into mature blood cells, which normally circulate in the blood stream. The high dose chemotherapy consists of cyclophosphamide and anti lymphocyte antibody (a protein that depletes cells that cause damage to the body). The purpose of the intense chemotherapy is to destroy the immune system completely. The purpose of the stem cell infusion is to restore the body's blood production, which will be severely impaired by the high dose chemotherapy and anti lymphocyte antibody.
Crohn's disease (CD) is a chronic illness, immunologically mediated, probably induced by the exposure of the intestine to an antigen or antigens similar to the intestine, to which immunologic tolerance is lost or a dysregulated immunity ensues. The disease has a variable course, from a mild, intermittently active illness requiring only symptomatic therapy to a fulminant illness requiring potentially dangerous immunosuppressive therapy, surgery or both. The molecular defect causing CD has not been characterized, but probably involves aberrant T cell function. Although CD often responds to immunosuppressive medication including corticosteroids, azathioprine and 6-mercaptopurine, to anti inflammatory drugs such as 5 aminosalicylate (5 ASA), or to some antimicrobial agents, including metronidazole, no therapy has been curative. In patients with severe CD, who have been unresponsive to corticosteroids, azathioprine, 5 ASA, metronidazole, and infliximab, we propose to compare the efficacy of Crohn's disease non-myeloablative autologous hematopoietic stem cell transplantation (CDNST) to standard therapy. Subsequent disease activity will be followed by (1) Crohn's disease activity index (CDAI), (2) a more global severity index, the Crohn's Severity Index, (3) type and amount of therapy for CD, and (4) clinical, hematologic and biochemical studies.
Crohn's disease (CD) is a form of inflammatory bowel disease that can affect any part of the digestive system. Symptoms of this chronic illness include abdominal pain, bloating, nausea, vomiting, and diarrhea. CD also causes bowel wall ulcers, strictures (narrowings of a hollow structure due to scar tissue and swelling), and fistulae (abnormal passages from the intestines to another organ or to the skin). CD is thought to arise from a combination of inherited (genetic) factors and some undefined environmental factor(s). One environmental factor that has been shown to be intimately involved with the development of CD is the presence of bacteria that normally inhabit the intestines. As a result, some physicians have tried to alter the normal bacterial population as a means of controlling the inflammation (swelling) in the intestines of individuals with CD. Among such strategies is the use of a combination of metronidazole and ciprofloxacin. These broad-spectrum antibiotics control CD symptoms by acting on the intestinal bacteria that can contribute to chronic inflammation. More investigation is needed to firmly establish the usefulness of this therapy because previous clinical trials have given mixed results, although they have suggested that antibiotics can be particularly useful in cases of Crohn's colitis (CD that primarily affects the large intestine). Because these earlier studies have lacked a large enough patient population with colonic involvement, a trial focusing on this CD subgroup with a sufficient number of subjects will help to clarify the value of combining metronidazole and ciprofloxacin. The proposed study will test the hypothesis that combination antibiotic therapy is effective in the treatment of CD involving the colon. The study will compare the use of combination therapy consisting of metronidazole and ciprofloxacin with placebo (dummy tablets) and will examine the results of treatment at the end of 8 weeks of treatment.
This study is aimed to assess the hypothesis that instillation of fibrin glue with the induction of local conditions using Infliximab, may be useful in the treatment of perianal Crohn's disease.
The purpose of this study is to visualize the healing effect on mucosal lesions with Pentasa Sachet 4g in patients with mild to moderate active small bowel CD by video capsule endoscopy.
The purpose of this study is to evaluate whether treatment with Leukine in patients with Crohn's disease who have previously responded to Leukine can be helped again, once they have relapsed.
The purpose of this study is to establish a safety profile sargramostim administered in 8 week cycles to adult patients with active Crohn's disease.
The purpose of this study is to observe pediatric Crohn's Disease response to sargramostim in patients with or without steroid therapy at two possible dosage levels.
The investigators will select 60 people who are 18-70 years of age with Crohn's disease and randomly assign them to receive an 8-week trial of celecoxib and an 8-week trial of a placebo. There will be a 1-week interval or "wash-out" between trials when the participant does not take any study medication. The investigators will monitor the participants for 18 weeks after they start the medication and observe their Crohn's disease activity, assessing for flare-ups or exacerbations in the disease and other possible side effects of celecoxib. Based on these observations, a determination will be made by the investigators as to the safety of celecoxib. If celecoxib is found to be safe, then it may provide physicians with a medication that they can prescribe for people who have Crohn's disease and experience chronic pain from arthritis and arthralgia.
